Solid Radiant Barrier Foil - 4' x 125' (500 sq ft)

Also available in 1,000 sq ft rolls. EcoFoil Solid Radiant Barrier Foil uses reflective technology to increase the energy efficiency and comfort level of your home. A radiant barrier is made of a thin layer of woven polyethylene which is sandwiched between two layers of a highly reflective metalized coating. With the polyethylene core, the reflective barrier cannot be ripped or torn. It blocks 96% of radiant heat transfer, helping keep your home cooler in the summer and warmer in the winter. The EcoFoil Solid Radiant Barrier acts as a foil vapor barrier when the seams are taped, keeping moisture from passing through it. This radiant barrier foil can be used in walls, roofs, floors and crawl spaces that require a vapor barrier. EcoFoil Radiant Barrier Foil can also be used inside the home on the bottom of the subfloor or joists as a radiant heat barrier, to keep heat contained either up or down, much like zone heating with an HVAC system.  An easy way to install would be to run the product perpendicular to your framing and staple into place. For new construction the radiant barrier foil would be installed under your sheathing to keep radiant heat out during the summer months and radiant heat in during the winter months. To install in crawl spaces, staple radiant barrier foil to the bottom of your joists, keeping the heat inside your living space which will prevent condensation and the possibility of mold from forming on the joists or subfloor. This 500 square foot roll is perfect for small spaces or to limit purchase of excess materials for your job.  R-Value Of Radiant Barriers Rather than rating by R-value, all radiant barrier products are measured by their reflective and emissive properties. EcoFoil radiant barrier foil is 96% reflective and 4% emissive, meaning the product only allows 4% of radiant heat to pass through. For more information on R-values, see our How It Works page or contact a member of our service team via chat, calling (888) 349-3645, or using the form here.   Important - You must use 3" Foil Tape on the seams of the material to ensure the product acts as one sheet and maintains the moisture barrier.
